Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they cook and bind it into a smooth emulsion.
- Butter
- Adds richness and body, helping the dressing feel smooth and creamy.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Provides acidity that gives the dressing its tang and helps preserve it.
- Mustard
- Adds sharp flavour and helps stabilise the emulsion.
The step that matters
Pouring the hot mixture over the egg mixture. Egg yolks thicken when heated but can scramble if they get too hot too fast. Pouring the hot liquid slowly while stirring constantly gently warms the yolks so the dressing thickens smoothly instead of curdling.
